Firmware Update Activates Power Nap Feature in Mid-2011 MacBook Air

Apple’s next version of OS X, Mountain Lion came out early Wednesday, adding over 200 new user features including Messages, Notification Center, Notes, and iCloud. Alongside some of the iOS like features introduced in the update, Apple also released a new feature via a firmware update in OS X 10.8 called Power Nap. PowerNap was previously announced at Apple’s WWDC 2012 and allows any Mac running the feature to receive email, update software, and syncing the calendar while the computer is sleeping.

Apple released a support document, highlighting the full abilities of OS X Mountain Lion. Full features of the update include: Syncing Mail, Calendar, Contact and Reminders as well as downloading software updates and Time Capsule backups. The Power Nap feature is currently only available on Mid-2011 Macbook Air and beyond as well as the new 2012 Retina MacBook Pro, both of which operate on SSDs (Solid State Drive).

Flashstorage is a requirement for the feature as it can operate faster and more efficiently, using less power. The update was brought to 2011 MacBook Air via a firmware update and is expected to appear on the Retina MacBook Pro, likely through another firmware update.
